Price-Driven Positive-Sum Game Offloading Strategy in Smart Grid enabled by 5G Cloud-Edge Collaboration

Abstract

As the key technology of the sixth generation (6G), cloud-edge collaboration has attracted people’s attention in smart grids. However, the complex network structure of cloud-edge collaboration not only requires a reasonable offloading scheme to deal with real-time traffic changes, but also requires an effective incentive mechanism to prompt servers to provide resources for users. This paper designs an offloading scheme in Smart Grid enabled by 5G Cloud-Edge Collaboration. On the one hand, a back-off mechanism is introduced to alleviate the contradiction between supply and demand of resources, and on the other hand, a dynamic pricing strategy is introduced as an incentive mechanism for the server. To minimize the user’s offloading cost, we propose a price-driven positive-sum game offloading(PPGO) algorithm, which can meet the different computing needs of users while ensuring server revenue. The simulation results show that the algorithm has good performance compared with other algorithms, and the back-off strategy can effectively alleviate the problem of insufficient computing resources.
